Hi i need help, im on my first grow, i have a 1.2x1.2x2 metre mylar lined grow tent and 600w hps with reflective hood
2 of my 3 plants (bag seed) are now over 2 metres in height and ive had to tie them down, the other one isn't far behind
i just bought a 4" inline fan ttvents with heat probe and temp/fan speed control although i havent it fitted yet and i dont have heat control other than a 12" fan hitting the light to distribute the heat better and the room sits at about 30C
im just hitting the 3 week of flower after 5 weeks veg, and my plants are developing some worrying leaves, its mostly the fan leaves that are affected but they have gone half yellow from the tips inward and have dark brown spots on the yellow bits
ive broke the worst ones off but i dont want to take to many off incase it affects it too much
im using canna nuits but have spent the last three days flushing and its not helping, am i having nuit problems or heat problems?
i know i havent posted much, i usually just search the forum for someone who has the same problems and see what answers they get, but im struggling to find anything on this one and i dont want to let it go any further incase i loose them.
will try to up some pics but im on dial-up cause i live in the arse-hole of nowhere. and i work 15 hours a day 7 days a week and only get about 20mins a day max to work on them, so anything i try it's 24hours before i can see if its working.
